T aZZ whom 2'5 may concern Be it known that I, WILLIAM S. VAN HonN, a citizen of the United States, residing at Cleveland, in the county of Guyahoga and State of Ohio, have invented certain new and useful Improvements in Scrapers for Ironing Machines, of which the following is a specification.

The present invention relates to ironing machines or mangles and the object of the invention is to provide a. scraper for removal of matter such as starch or the like that might adhere to the roller of the machine. If such foreign matter were permitted to re main on the roller during its operation, it

would soil the clothing being ironed and make ugly blotches or spots on an otherwise clean garment or it might cause the tearing of thin, delicate material.

In the accompanying drawings, one embodiment of the invention is illustrated and Fig. 1 shows a top plan view partly in section of an ironing machine or mangle with the scraper attachment in position;

Fig. 2 is a section along line 2- 2 of Fig. 1 and Fig. 8 is a perspective view of some of the details.

In the figures reference numeral 9 represents a table secured to a stand 10 upon which the ironing roller 11 is mounted in supports 12 in the usual manner and at one end of the roller is provided a pulley 13 driven by a belt 1 1 from a suit-able motor. Reference numeral 15 represents a shoe or heating plate for the roller also mounted in the supports 12. The described details constitute parts of an ordinary ironing ma chine and form no part of the present invention.

Alongside the roller 11 is provided a straight edge 16 which is preferably mounted about midway up on the roller and parallel with the axis thereof. The straight edge 4 ts under a longitudinal board 17 secured on the stand 10 above the table top 9 permitting movement in horizontal direction of the straight edge 16. Normally the straight edge 16 projects beyond the inner edge of the board 17 and abuts against the surface of the roller but at times it may be retracted so as not to protrude beyond the board, when it does not obstruct the passing of clothing or fabric that is going to be ironed on the roller 11.

The straight edge 16 is supported on a pair of short rods 18 secured at the outer edge thereof and carried in housings or brackets 19 rigidly secured against the bottom side of the board 17. Each of these housings has a half round chamber 21 through whichv the rod 18 extends outwardly and the chamber is formed with abottoin 22 against which one end of a coiled spring 23 abuts; hile its other end abuts against a shoulder formed on the rod 18. In this manner the weight of the straight edge 16 and the rods 18 is sup ported in the housings 19 together with both the coiled springs 23, which are tensioned so as to exert a centripetal pressure tending to hold the straight edge against the cylindrical surface of the roller 11.

The outer end of each rod 18is threaded for the purpose of receiving a clevis nut 24, to which is pivoted a lever 25 having an oblongslot 26 engaging a pin 27 carried by the clevis 24, so as to permit a. slight longitudinal travel between the parts. The levers 25, which are two in number. are fulcrumed respectively at v28 and 29 in the board 17, and are extended so as to meet medially between the housings 19. The inner ends 30 and 31 of the levers engage with an eccentric 32 journaled as at in the board 17.

The roller 11 is preferably covered with a felt lining or padding 20, upon which the material to be ironed is placed.

With the parts in the relative positions shown in Figs. 1 and 2 the cam portion of the eccentric 32 with the shorter radius contacts with the ends 30 and 31 of the levers 25, so that the latter stands in substantially aligned position, indicated by full lines, and the springs 23, now being released, will push the straight edge 16 inwardly until it abuts against the surface of the roller 11, which is in this manner cleaned and scraped while the roller rotates. 7

With the eccentric 32 swung with its handle 34 in the opposite direction indicated pressed and the straight edge 16 retracted through the intermediary of rods 18 and placed flush with theedge 30 of the board 17, see Fig. 2. In this position the straight edge will form no obstruction during the ironing process. In order toobtain the best results during the ironing of garments or other material, it is advisable to permit the straight ed e 16 to clean and scrape the roller before placing a fresh garment upon the table for ironing, and the handle 3% of the eccentric 32 is accordingly placed in most convenient position for the operator to perform this scraping process without stopping the machine without any loss of time. It is accordingly claimed, that this device saves as otherwise the operator would constantl have to wipe off the roller to insure that no foreign matter adhere thereto.

The scra er or straight edge 16 has stil another function, namely to loosen or peer 03 any light material, such as curtains, lace and the like, that would otherwise adhere to the roller 11 from the action of the starch. during operation. it ordinarily requires two persons to operate ironing machine of this character, one pcrsonto "feed the material over the roller and under the hot shoe to keep the material straight; and another person for loosening the material from the roller after ironing and prevent it from passing around the roller a second time. After ironing, the dried or hardened starch would naturally tend to retain the thin material on the padding 20 or the roller, but a second and very important function of the scraper or straight edge is. now to detach such material from the roller and drop it upon the table top 9 underneath.

This saves time and labor as only one op erator would be needed to manage In ma chine, while ordinarily the person feeding the material to the roller standing in front or the machine would not he able to see whether the material adhered to the roller or not. from the roller 01" its own weight and drops on the table 9.

Having thus described the invention, what is claimed as new is:

1. The combination with an ironing roller and a support thereforof a straight edge mounted in said support parallel with said roller and means for reciprocating the straight edge as regards the roller, said means including yieldahle elements tending to press the straight edge along radial plane against the roller and guides and retra ting members for aid elements.

2. The combination with an ironing roller and a support therefor; of a straight edge mounted in said support parallel with said roller and means for reciprocating the straight edge as regards the roller, said means including rods carrying the straight edge, housings for said rods, springs in said housings engaging with said rods and tending to press the straight edge against said roller and members connected with said rods for retracting the straight edge.

T he combination with an ironing roller and a support therefor; of a straight edge mounted in said support parallel with said roller and means for reciprocating the strai ht edge as regards the roller, said means incl ding rods carrying the straight edge, housings for said rods, springs in said housings engaging with said rods and tend to press the straight edge against said roller, levers pivoted on said support and having hinged connection with said rods, and an eccentric coacting with said levers to retract the straight edge.

In testimony whereof I affix my signature.
